c - Blocked Compressed Row Storage format of Sparse Matrix -

-

I am writing a program that will change the spurs matrix for compressed cry storage.

I know how to get Ropert, Collind (not in code) and A_F.

Code: 

  p = 0; {Row_ptr [++ p] = (row_ptr [p-1] + count_blocks (A, I, N)) for (i = 0; i & lt; m; i ++); (J = 0; j & lt; n; j ++) (if (a [i] [j]) {a_f] [a] = a [i] [j]; k ++}}}}   
 The function I use gives the number of blocks in the row:  
  int count_blocks (int matrix [100] [100] (I = 0; i & lt; n - 1; i ++) {if (matrix [row_idx] [i]) {if (!), For int row_idx, int n) {int i; int block_count = 0; Block_count ++; else if (row_idx] [i + 1] and am == n - 2) I] and am == n - 2) {if (matrix [row_idx] [i + 1]) block_count ++; breakdown;}} return block_count;  
 
 But I got trapped in getting NPTRR. 
 
 Thanks :)

Here's a function that gives nzptr 5x5 size metrics. It gives the number of items in nzptr , it also calculates the index with cylindrical indexing. 

  int computeNzptr (double matrix [5] [5], int njptr []) {int isNewBlock = 1; Int nzIndex = 0; Int nonZeroCount = 0; Int i = 0; Int j = 0; (I = 0; i & lt; 5; ++ i) {for (j = 0; j & lt; 5; ++ j) {if (matrix [i] [j]! = 0.0) {++ nonZeroCount ; If (isNewBlock) {isNewBlock = 0; NZTPR [NJIDX ++] = Non-Xerocount-1; }} Else {isNewBlock = 1; }}} Return nzIndex; In the context image, descriptions and answers do not match.

PS

When you have 5x5 metrics, which are similar to the matrix in the posted image, 

  double matrix [5] [5] = {{5.0, 1.0, 7.0, 0.0, 0.0} , {0.0, 2.0, 0.0, 2.0, 3.0}, {0.0, 2.0, 4.0, 0.0, 0.0}, {0.0, 0.0, 1.0, 3.0, 0.0}, {0.0, 6.0, 0.0, 0.0, 0.0, 3.0}}; The output should be according to the details:  
  0 3 4 6 8 10 11  
 
 in reference Different from output 
 
 I agree that the description of the reference document is correct and the output is incorrect.

java - Gradle dependencies: compile project by relative path -

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...

So I have participated in a glitch error that I do not even know how to debug. I am very new to the railing, so it has kicked my ass well when I use the .includes (school) seen by the student, it gives a blue box error, But when I look at any other model and .includes (school) , the school works just fine. class student & lt; ActiveRecord :: Base has has_many: relationships, foreign_key: "liker_id", dependent :: has_many: matches, foreign_key: "student_1_id", dependent :: deleted belong_to: school belong_to: conference belong_to: would_you_rather belong_to: home city belong_to: year is_to: Major and class school & lt; on the console activatecord :: Affiliate for the base: conference includes: respondent, class: "school", foreign_key: "rival_id" (e.g. For: School) Select SQL generated Select "School". * "School" from "school" "ID" IN (1) error message back NoMethodError: u...
